Well, on the homepage it's a little hard to see the letters. If you add a glow or a blur on the background image you'll be able to see it better. Also, if the top menu weren't so tall and maybe the font size on the menu would be nice. The size it is when you scroll down is perfect but it looks a little odd due to the small font size. Also, don't use images as a button. It looks weird. Just make a CSS button and it'll look good
